The bottles form the trapezoidal shaped, rhombic shaped and inverted trapezoid shaped comprising that: a main body of bottle consisted of a first portion, second portion and bottleneck portion; a first cutting surface and second cutting surface are formed between first and second protruding and third and fourth protruding for easily cutting along the cutting guide. The main body of the bottle is separated into the first portion, second portion and bottleneck portion by cutting along with the first and second cutting surfaces. So that, the volume of the disposed bottles is reduced by separating and overlapping the parts, while the plastic bottles are recycling.

BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a plastic bottle forming cutting guide. More particularly, a bottle for containing a liquid substance, such as a water or beverage is configured a cutting guide to easily cut for separating and stacking the bottles.

Therefore, the volume of disposed bottles could be reduced to minimize the recycling package by cutting and separating the bottles.

2. Related Prior Art

Generally, the PET (Polyethylene Terepthalate) (hereinafter ‘Pet’) bottle is harmless to the human body. The pet bottle is recyclable, and does not generate a hazardous fume while it is burning.

In addition, the PET bottle has excellent isolation effect from the carbon dioxide and oxygen, so that it is suitable to store the substance for a long-period without deteriorating its contents. The weight of the Pet bottle is lighter than the glass bottles or the metal cans. The Pet bottle also has properties of the excellent formability and transparency. Thus, it is widely used as a storage container to contain a liquid substance, such as a spring water, beverage, alcoholic beverage and liquid food, etc.

On the other hand, the Pet bottles are generally made of the plastics, such as a thermoplastic resin. Such a thermoplastic resin will be softened or melted, when the heat is applied to. The molten resin is pouring into a Mold to form various shapes of bottles according to the shape of the Molds. The plastic has a property of formability. However, it will be hardened when the molten thermoplastic resin is cooled down.

For example, a method of producing Pet bottle by using such a thermoplastic resin is adopted an injection blow molding (Injection Stretch Blow Molding) process. The injection blow molding is applied to produce the hollow products, such as a bottle. This molding method is called a blow molding (Blow Molding). Such the injection blow molding method is generally applied to the thermoplastic resin. There are various Molding methods those are the extrusion blow molding, injection blow molding, and injection stretch blow molding.

As an example, the Republic of Korea Patent Application No. 10-2008-0044663 discloses a background technology, which produces conventional pet bottle by using the thermoplastic resins as described above.

According to the conventional technology of the Pet bottle, as shown in FIG. 1, a drinking water container (10) is consisted of a main body portion (11), lower containing portion (12), upper tapered portion (13), bottleneck portion (14) and the cap (15). Excluding the cap (15), the Pet bottle is integrally made of thermoplastic transparent resin as a raw material by injection molding process.

The Republic of Korea Patent Application No. 10-2008-0044663 (the title of the invention: PET beverage containers) is filed on May 14, 2008 by the applicant: Lotte Aluminum Co., Ltd.

SUMMARY OF THE INVENTION

However, the PET bottle according to the conventional technology, the hollow portion of the bottle occupies a very large proportion by volume, so it will be bulky packing when it is disposed. There is the disadvantage that a large amount of garbage bag is unnecessarily consumed, and occupied large storage space.

Further, according to the conventional technology, the discarded PET bottles are collected through many different routes for recycling. At this moment, the bulky volume of the disposed bottles is raised a big problem. The volume of bulky recycling packages will cost to collect and inconvenient to transport.

The object of the present invention is to solve the above mentioned problem. A main body of the plastic bottle has formed a cutting guide along the outer periphery. The cutting guide is a pair of raised borders and a groove between the raised borders to easily cut along the groove.

For example, the bottle is configured to easily cut by using a cutting means, such as a knife cutter, so that the separated bottle parts are overlapped to stack a plurality of disposed bottles. Thus, it is continent to handle the bulky empty bottles for recycling.
